Description
Opuntia microdasys var. pallida f. cristata is a clump-forming cactus with unusual, green, wavy pads adorned with bright yellow glochids arranged in dense clusters. It can grow up to 2 feet (60 cm) tall. The distinctively shaped pads can reach up to 6 inches (15 cm) in length.
The flowers are yellow, appear in spring, and can reach a diameter of 2 inches (5 cm).

How to Grow and Care for Opuntia microdasys var. pallida f. cristata
Hardiness: USDA hardiness zones 9a to 11b: from 20°F (-6.7°C) to 50°F (10°C).
A spot near a south-facing, unobstructed window will likely meet Bunny Ears Cactus's need for bright, direct sun—windows with western or eastern exposure are the second- and third-choice options. While an actively growing Bunny Ears Cactus tolerates indoor summer temperatures as high as 100°F (38°C), don't expect it to flower unless you also provide winter temperatures between 45°F and 55°F (7°C and 13°C). Regardless of the season, it prefers humidity in the 10-30% range. Finally, if none of your windows provide adequate light, place the plant 6 to 12 inches (15 to 30 cm) below a cool, white fluorescent tube for 14 to 16 hours daily.
The potting soil must drain quickly. Use a commercial cactus potting mix or mix your own. The best container for your cactus is a clay pot, just slightly larger and deeper than the plant's root system. It must have drainage holes, because a pot without them, or one that's too large, could make proper watering impossible.
